I just like to think that a Japanese will take my premise someday and make some changes I shouldn't expect.
Only the MC is ethnically Japanese, as the setting is an alternate fantasy world ressembling a medieval Earth with non-Japanese names. The anime will be a half-sarcastic action comedy that makes fun of current fantasy anime trends such as battle academy harem, survival action and isekai fantasy all combined into one.
Shounen is not a genre, it is a demographic for series aimed at younger males regardless of change. Since the anime will air late at night, it will pander to seasonal otakus.
